    • Breaking the Symmetry Between Interaction and Replacement in Evolutionary Dynamics on Graphs 

      Ohtsuki, Hisashi; Nowak, Martin A.; Pacheco, Jorge M. (American Physical Society, 2007)
      We study the evolution of cooperation modeled as symmetric 2×2 games in a population whose structure is split into an interaction graph defining who plays with whom and a replacement graph specifying evolutionary competition. ...
    • Pairwise Comparison and Selection Temperature in Evolutionary Game Dynamics 

      Traulsen, Arne; Pacheco, Jorge M.; Nowak, Martin A. (Elsevier, 2007)
      Recently, the frequency-dependent Moran process has been introduced in order to describe evolutionary game dynamics in finite populations. Here, an alternative to this process is investigated that is based on pairwise ...
    • Repeated Games and Direct Reciprocity Under Active Linking 

      Pacheco, Jorge M.; Traulsen, Arne; Ohtsuki, Hisashi; Nowak, Martin A. (Elsevier, 2008)
      Direct reciprocity relies on repeated encounters between the same two individuals. Here we examine the evolution of cooperation under direct reciprocity in dynamically structured populations. Individuals occupy the vertices ...
    • Stochastic Payoff Evaluation Increases the Temperature of Selection 

      Traulsen, Arne; Nowak, Martin A.; Pacheco, Jorge M. (Elsevier, 2007)
      We study stochastic evolutionary game dynamics in populations of finite size. Moreover, each individual has a randomly distributed number of interactions with other individuals. Therefore, the payoff of two individuals ...
